Migrate to new server(s)?

Just wondering if there is a how-to on moving to a new server. Currently I am using the VMware template build, but want to build a new server with CentOS 7 and migrate all the data and processing to the new system. Any advice would be greatly appreciated.
See-ya

That's actually my bad, not yours GhostRider2110. One of my coworkers spotted my mishap - I gave you instructions for NagiosXI, not Log Server. We get so many more requests for XI support than our other products it totally escaped me to think about what product you're actually asking about and I defaulted to our flagship product.
I'll leave it for my other colleagues to go into details, but basically the process isn't to backup from an old server and restore to new, but rather to phase in new than phase out old.
Again, my apologies for answering the wrong question!

Here's one way without having downtime.
Perform a fresh install of Log Server on the new box. Then navigate to the web page on the new box and add this new server to the existing cluster.
Now you have two nodes in the cluster.
Then point all your existing devices to the IP address of the new log server.
Once all the data from the first cluster has been replicated to the second cluster, then you should be able to remove the old node from the cluster.
I'll need the Log Server Dev's and Tech's to verify this solution.
